What is the slope of the line between (-4,4) and (-1-2)? please help i have little time I know this is easy, but I did it and the answer is not one of the choices :( I got -3, but the choices are: 1 ,2, -2, or -1.

if youre trying the formula, then you are most likely like me and have placed something in the wrong spot

(-4,4) will be (x1,y1) (-1,-2) will be (x2,y2)

then it will be: -2-4 over -1- (-4) = -6 over 3 = -3

i do a vertical method, subtracting down the columns (-4,4) -(-1-2) ------- (-3,6) , now slope is defined as y/x 6/-3

wait what.. i did it so wrong

you just subtract?

that's not how we were shown to do it so i dont think i could do it that way..

my method is to stack one point on top of the other, and subtract down the columns

that's not the right way to do it though..

it is the right way to do it ...

look how i did it ^^

\[\frac{ -2-4 }{ -1-(-4) } - \frac{ -6 }{3 } = -2\] ohhhhh

i just put -6 divided by 3 = -3, instead of -2!!!!!!!!!

ok that's the stupidest mistake ever

take 2 points: (xo,yo) and (x1, y1) stack them and subtract (its just a method to organize the information) (xo,yo) -(x1, y1) --------- xo-x1, yo-y1 , you still get the same information; now slope is defined as y/x yo - y1 ------- xo - x1

i just waste 5 mins

since i tend to place the wrong value into the wrong places .... i organize the data in a more convenient manner that is harder to mess it up
